- These are Micro Channel Ethernet adapters. You need to say Y to "MCA

-Copyright 1999 by Alfred Arnold (alfred@ccac.rwth-aachen.de,

-
- A big thank you to the S&K support for providing me so quickly with
- documentation!
-
- Also see http://www.syskonnect.com/
-
- Missing things:
-
- -> set debug level via ioctl instead of compile-time switches
- -> I didn't follow the development of the 2.1.x kernels, so my
- assumptions about which things changed with which kernel version
- are probably nonsense
-
-History:
- May 16th, 1999
- startup
- May 22st, 1999
- added private structure, methods
- begun building data structures in RAM
- May 23nd, 1999
- can receive frames, send frames
- May 24th, 1999
- modularized initialization of LANCE
- loadable as module
- still Tx problem :-(
- May 26th, 1999
- MC2 works
- support for multiple devices
- display media type for MC2+
- May 28th, 1999
- fixed problem in GetLANCE leaving interrupts turned off
- increase TX queue to 4 packets to improve send performance
- May 29th, 1999
- a few corrections in statistics, caught rcvr overruns
- reinitialization of LANCE/board in critical situations
- MCA info implemented
- implemented LANCE multicast filter
- Jun 6th, 1999
- additions for Linux 2.2
- Dec 25th, 1999
- unfortunately there seem to be newer MC2+ boards that react
- on IRQ 3/5/9/10 instead of 3/5/10/11, so we have to autoprobe
- in questionable cases...
- Dec 28th, 1999
- integrated patches from David Weinehall & Bill Wendling for 2.3
- kernels (isa_...functions). Things are defined in a way that
- it still works with 2.0.x 8-)
- Dec 30th, 1999
- added handling of the remaining interrupt conditions. That
- should cure the spurious hangs.
- Jan 30th, 2000
- newer kernels automatically probe more than one board, so the
- 'startslot' as a variable is also needed here
- June 1st, 2000
- added changes for recent 2.3 kernels
